Specification of Letters Patent.

Application filed August 15, 1913.l Serial No. 784,939.

ToaZ'Z who/m, t may concern Be it known that I, Tniionoim Weno, a citizen of the United States, residing 'at Jacksonville, in the county of Duval and State of Florida, have invented. new and useful Improvements in Sprayers', 'of which the following is a specic'atlon.

This invention is 'an improved sprayer adapted for 4use in connection with a hose for sprinkling lawns and other like uses and embodying essentially a support for connection with a hose and having an intake duct, a rotor carried b the support and against which the inta e duct discharges and 'a discharge tube extending from and revolved by the rotor, the invention further consisting in the construction, combination and arrangement of devices hereinafter described and claimed. y U

One object of my invention is to provrde an improved sprayer which is extremely cheap and simple, is strong and durable and the'parts of which may be readily assembled and disassembled. I I

Another object is to effect improvements in the construction of the casing of the rotor whereby a member of the casing is also utilized as a cone for the reception of bearing balls which minimize friction in the bearin of the rotor.

In t e accompanying drawing :-F1gure 1 is an elevation of a sprayer constructed in accordance with my invention, with a portion of the cover of the casing removed. Fig. 2 is a vertical central sectional view of the same. Fig. 3 is a transverse sectionalview of the same on the plane indicated b the line -a of Fig. 2. Fig. 4 is a detail plan of the body or lower portion of the casing or support. Fig. 5 is an inverted plan of the rotor.

In accordance with my iitivention,y I provide a suitable support which is here indi# cated at 1 and Specifically consists of a body or main member 2 and a cover 3. The boch7 2 is circular, is provided with screw threads and on its under side has a centrally arranged shank 4 which is formed witha polylgonal iange 6 adapted to be engaged by t e hand or b a wrench when attaching the body to a ose or removing the same therefrom.

The shank of the body is provided with a centrally located threaded opening 7 adapted to be screwed to a coupling member at one end of a hose and from the said opening 7 extends an intake duct 8 which is arranged spirally, diminishes diametrically toward its discharge end, and the ,discharge end 9 of the duct is at the plane face 10 of the body and at a point a suitable distance from the center thereof. The number of these intake ducts is optional, one being here shown. The bod 1 of the support or casing is also provi ed with a segmental baiile 11 which projects from the plane face 10 of the body and is arranged with one end between the discharge end of the duct and the center of the body, as shown in Fig. 4. The number of these baffles is also optional and should correspond with that of the intake ducts'.

The cover 3 of the casin has a portion 12 which is internally threa ed and is adapted to be engaged with the threaded portion of the body so that the cover may be readily attached to and detached from the body and may be also adjusted thereon. The cover is also formed with 'a circular chamber 13 and with a central corneal ortion 14, the latter forming a collar to which the inner end of a.

.bea-ring sleeve 15 is attached, preferably by soldering.

The body 1 may be avcasting, the cover 3 is Preferably made of pressed brass or other similar material and the bearing sleeve 15 is preferably a short portion of a brass tube. Hence, the body or casing of my improved sprayer may be very readily and cheaply manufactured` A rotor 16 is arranged for revolution in the chamber 13 of the cover of the casing and on the face 10 of the body of the casing. This rotor is here shown as provided on its under side, or that side which is opposed to the face 10 in the body of the casing with a centrally located chamber 17 and with a series of radial and obliquely arranged blades 18 which project from the fcircular wall 1'9 of said chamber. The ulpper side of the rotor is closed as at 20, t

Espaces between the blades 18 form peripherally arranged buckets and openings 21 are made through the wall 19 and which establish communication between the central chamber 17 and the buckets or spaces between the blades of the rotor. The diameter of the chamber 17 is suchthat the segmental baiiie 11 of the body of the casing is arranged ju'st within" and in close proximity to the wall 19 and it will be observed that the baiiie serves to cut off one or more of the openings 21 in succession as the rotor revolves and, moreover, that the openings 21 permit the passage of water from the buckets of the rotor inwardly to the chamber 17 thereof, the water then passing from therotor out through the bore of a tubular shaft 22 with which the rotor is provided.

The buckets of the rotor 1n succession pass over the discharge opening 9 of the intake duct of the body of the casing and, hence, the said intake duct discharges against the blades of the rotor and the latter is caused to revolve. The tubular shaft 22 of the rotor is arranged in and projects through the bore of the bearing sleeve 15. A suitable number of bearing balls 23 are arranged in the cone 14 of the cover and bear on the rotor in the angle between the outer side thereof and the inner end of the tubular shaft. These bearing balls in connection with the cone form a ball bearing for the rotor so as to minimize friction and promote the-rapid revolution oi the rotor and it will be understood that the cover 3 of the casing may be adjusted on the body 1 to take up wear at any time between the bearing balls, or against the rotor, should the same become necessary, and also to prevent binding on the bearing balls.

To the outer end of the tubular shaft 22 of the rotor is attached a discharge tube or nozzle 24 which is curved longitudinally so that its discharge end isv eccentric to the rotor and, hence, as the rotor revolves and the water passes therethrough and out through the discharge nozzle it is eifectually sprayed by the rotation of the nozzle and discharged as it is sprayed on the grass, flower bed, or according to the use to which the sprayer is applied.

It is obvious that the sprayer may also be used for applying disinfectants to trees and plantsand for washing carriages, windows and other analogous uses and I would have it understood that I am not limited in this particular.

While I have herein shown and described a preferred form of the invention, I would have it understood that changes may be made in the form, proportion and construction of the several parts without departing from the spirit of the invention and within the scope of the appended claims.

I claim:-
